Hi all
I have MSI gaming 7
4790k
nactua d-15
Kingstone beast 2×8gb 1600
Tried to google this items but no guide were find can anybody guide me?
or post a link for this matter?

On msi gaming 7 make sure you put the cpu ratio to fixed mode as well, after you've changed the cpu ratio. And you're making sure it is only cpu core voltage and not ring voltage you are changing right?

Make sure your VCCIN voltage is set to around 1.7 or 1.8

Every motherboard will be slightly different and maybe list things differently but the overall principle is the same. There's a guide right above in the sticky that will tell you about testing and such once you've found a stable overclock but with the chips today, they are so easy to do it's just a matter of changing a few things.

The easiest way is just to change your core values or multipliers, it may be worded different in each mobo but it is the same thing. As you go up in frequency speed, you will also have to increase voltage. You want to increase your voltage manually because auto usually applies too much voltage. These are both located in your bios and may be under an overclocking tweaker or in advanced but they are there.

It is really just a matter of finding the least amount of voltage you can use with the increase in frequency and then passing your stress tests for temps and stability and testing them n games.

I would try to stay under 1.3 volts to the vcore. That is the only voltage you want to change, there is another way using voltage offsets but it is a more in depth process and takes longer to reach stability. You can go above 1.3V but anything under should not affect longevity of the chip or anything so above is at your own risk, although overclocking is a risk anyways but there's a reason they make the K chips, they are tough little processors and can handle overclocking.

If you want to start easiest way...increase vcore to 1.25V and then change your multiplier(core values) to say 4.4 or 4.5 Ghz, this may be written as 44 or 45 in the bios but is the same thing. Then save and apply everything, reboot come back in windows and run a few tests. I use OCCT, the intel extreme testing utility and there is a version of prime 95 you can run, just don't use the latest version. I'll see if I can find it, but the latest prime 95 is not the best for the intel chips.

After you find enough voltage to pass tests, for where you want to be, you can always fine tune it more and see if you can lower the voltage anymore...it all depends how much time you want to invest in it.

guys thanks to the quick reply
i know about the core voltage but what about North B. and other voltage setting ? i have so many
my target is 4.7 that's why i gut the d-15
so let my get started and update you i will try 4.4 at 1.20
stay tune

Well at the moment on bios and i came across an little obstacle i have line that i know i need to change on voltage settings it's called
Cpu core/ring/gt voltage mode its on auto
And my options are
Auto
Adaptiv mode
Override mode
Offset mode
Adaptive+offset mode
Override+offset mode
Can anybody explain thos modes and what shuold i go for

I didn't change it on mine, I left it on auto. Don't change any other voltage settings except for vcore and the VRIN or VCCIN but thats only when you start to oc really high, it should be set high enough now. It should be .4v or more above your vcore and mine is auto set at 1.8V.

1.2 probably too low. I'm at 1.257 for 4.6 and for 4.7 I was at 1.33Vcore. My 4.5 and 4.4 overclocks are at 1.24 I think, I didn't try to lower them as much as I could as I stay at 4.6 or 4.7 all the time anyways. That was the lowest I could go at 4.6 and 4.7 and be stable. Every chip is different too so what I run mine at will be different from you and you may have less or more voltage for the same frequency.

yes but on idle the voltage are low and cpu-z shows current voltage because the voltage going up only when cpu load gets up i think it's because the setting that i listed earlier adaptive mode offset so i cant see what current v. the com. freeze immediately
with MSI Command Center i do see that the voltage as changed
